second banana

The phrase "second banana" is an idiomatic expression used to refer to a person in a subordinate or supporting role, particularly in a comedic or entertainment context. It originated from the comedic practice of having a lead comedian or performer, known as the "top banana," and their comedic partner, known as the "second banana," who would provide comic relief or support the top banana's act. It can also imply being the second-in-command or having a lesser status or importance in various other situations beyond comedy.
